CAR-STAKE Specification of Letters Patent.

Patented Aug. 10, 1909.

Application filed march 2', 1909. Serial No. 480,825.

T 0 all whom it may concern:

Be it known that I, FRANK SHILLIN, citizen of the United States,residing at, Sundby, 1n the county of St. Louis and State of Minnesota,have invented certain new and useful Improvements in Car-Stakes, ofwhich the following is a specification. V I p This invention relates tocar stakes and has for its object the provision of a strong, durable,and efficient device of this character especially designed forattachment to a logging car or similar vehicle for thepurpose ofretaining the logs in position on the platform of the car duringtransportation. i

A further object of the invention is to provide a skidding attachmentfor use in connection with the car stake to facilitate loading or pilingthe logs or timber on the,plat form of the car.

A further object is to provide means for locking the stakes on bothsides of the car in a vertical or operative position, and means operablefrom the opposite ends of the car for releasing the locking meanstherebyto permit the discharge of the logs from either side of said car.

Further objects and advantages will appear in the following description,it being understood that various changes in form, proportions, and minordetails of construction may be resorted to within the scope of theappended claims.

For a full understanding of the invention and the merits thereof andalso to acquire a knowledge of the details of construction and the meansfor effecting the result, reference is to be had to the followingdescription and accompanying drawings, in which:

Figure 1 is a perspective view of a logging car provided with a stake01' standard constructed in accordance with my invention Fig. 2 is a topplan view of one end of the car; Fig. 3 is a perspective view of aportion of one of the bolster plates showing the locking mechanism; Fig.4 is a transverse sectional view taken on the line 22 of Fig. 2; Fig. 5'is a top plan view showing the operating shaft extending the entirelength of the car. Corresponding and like parts are referred to in thefollowing description and indicated in all the views of the drawings bythe same reference characters.

The improved stake or standard forming:

ging cars or similar vehicles, and by way of illustration is shown inconnection with a logging car of the ordinary construction in which 5designates the body of the car, and 6 the transverse bolsters secured inany suitable manner to the platform thereof. Secured to the inner andouter faces of the transverse bolsters 6 are metallic plates 7 the freeends of which are projected laterally beyond the adjacent longitudinaledges of the car to produce sockets 8 for the reception of the stakes orstandards indicated at 9. Secured to the opposite longitudinal edges ofeachstandard or stake at the upper portion thereof, are segmental plates10 forming conveX bearing surfaces 11 for engaging the logs or timberwhen loading the same on the platform of the car. I

The upper portion of th lates 10 are extended vertically above t e topsof the stakes and are connected by suitable transverse pins or bolts 12for en 'agement with flexible binding members or chains 13. The chains13 are each preferably formed in two sections,the long section of whichis secured to the transverse pin 12 on one side of the car, While theshort section thereof is secured to the transverse pin of the stake onthe opposite side of the car and is provided with a terminal hook 14arranged to engage any one of the links of the long section, said chainsections serving to prevent spreading of the stakes or standards whenthe logs are in position on the platform of the car. The conveX bearingsurfaces 11 of the plates 10 are also projected laterally beyond theadjacent longitudinal edges of the stakes 9 to permit the insertion of apin or bolt 15 so that a suitable skid 16 may be supported in engagementwith the stake for the purpose of lacilitating loading of the logs ortimber on the platform of the car.

The upper end of the skid 16 is provided with a terminal hook 17arranged to engage the transverse pin 15 of the adjacent stake orstandard thereby to prevent accidental displacement of the skid duringthe loading operation. Secured to the central portion of each stake orstandard is a staple 18 to which is connected one end of a short chainsection 19 for the purpose of supporting an intermediate binding memberor chain 20, the latter being provided with terminal loops or eyes 21,as shown. Each short chain section 19 is provided with a runner or ring22 whlch 1s slidably mounted on the adjacent staple or guide 18 and isprovided with a hook 23 which passes through the loop 21 for engagementwith a similar loop 24 carried by the chain section 19 thereby tosupport the intermediate chain section 20 in proper posi- 7 tion and atthe same time allow a slight verof the logs. each bolster on oppositesides of the adjacent tical movement of the chain so as to preventbinding or wedging action between the parts.

In the transportation of the logs, the latter are usually piled in twotiers on the platform of the car, and in order to facilitate the readydischarge of the logs of either tier, means is provided forsimultaneously releasing the stakes or standards on either side of thecar at said tiers. The 'stake releasing means comprises spacedlongitudinally disposed shafts 25 one of which is extended transverselythrough each set of bolsters 6 and is provided at its outer endwith anangular terminal 26 for engagement with an operating key, not shown.Pivotally mounted on the opposite ends of each transverse bolster 6 areco-acting locking members 27 which extend across the standard receivingsockets 8 when the stakes are in operative position and serve to retainsaid stakes or standards in position on the car during thetransportation Secured to the outer plate 7 of transverse shaft 25, arebrackets 28 which form keepers for the adjacent ends of locking membersor levers 29, the opposite ends of which are mounted at 30 on suitablesupports secured to said plate. Fastened in any suitable manner to eachbracket 28 is a casing 31 having oppositely disposed longitudinal slotsformed therein in which is slidably mounted a locking plate 32, thelatter being normally and yieldably supported at the rear of theadjacent locking lever 29 by a coil spring 33 mounted on an actuatingrod 34 and having one end thereof bearing against the casing 31 and itsopposite end engaging the plate 32, as best shown in Fig. 3 of thedrawings. Fastened in any suitable manner to each locking lever 29 is ahook 35 to which is secured one end of a chain or flexible medium 36,the intermediate portion of which passes around the locking members orplates 27 of the adjacent bolster for attachment to an eye 37 carried bythe plate 7 on the opposite side of said bolster. interposed betweeneach lever 29 and the face of the adjacent bolster is a sprin 29 whichserves to force the lever 29 lateral y when the adjacent locking plate32 is released and thus allow suflicient slack in the chain 36 to permitthe end of which is secured to an eye 40 carried by a sleeve or drum 41on the adjacent end of the shaft 25, as shown. The eye 10 is extendedthrough the sleeve or drum 41 for attachment to the shaft 25 whereby thetwo parts arefree to rotate in unison, there being a collar 42 securedto the adjacent bolster and forming a bearing for the sleeve or drum 41.and also serving to assist in preventing lon gitudinal movement of theshaft 25 with respect to the body of the logging car. Thus it will beseen that by positioning a wrench or similar tool on the angularterminal of either shaft 25 and rotating the latter in one direction,the adjacent chain 39 of one of the actuating rods 34 will be wound uponthe drum or sleeve 11 and thus exert a longitudinal pull upon saidactuating rod thereby to release the locking lever 29 so as to allowsuflicient'slack in the chain 36 connected with said locking member topermit the locking plates 27 to be moved to open position and thusrelease the adjacent stake or standard so that the logs may bedischarged. from the side of the car in the usual manner.

When the shaft 25 is rotated in the opposite direction the lockingmembers 29 of the stakes or standards on the op )osite side of the carwill be released in a simi ar manner so as to permit the discharge ofthe logs or timber on that side of the car. It will of course beunderstood that the connecting chains 39 will be sufliciently slack topre vent tension of one of said chains when the other chain is beingoperated to Oil OCt the release of the locking members on the other sideof the car. Thus it will be seen that the operator or other attendantmay stand at either end of the logging car and by rotating the adjacentshaft 25 in either direction effect the release of the locking membersof one or both tiers on one side of the car, and by rotating the shaftsin the opposite direction release the stakes or standards on theopposite side of the car so that the logs of either or both of the tiersmay be discharged from either side of the car simultaneously. If desiredhowever, the central longitudinal shaft, instead of being formed insections may be continuous, as shown in Fig. 4 of the d rawing, such aconstruction being desirable when the logs are not piled in tiers on theplatform of the car. It will here be noted that the convex edges of theplates 10 form a smooth bearing surface for engagement with the logswhen thelatter are loaded on the platform of the car, while theintermediate connecting medium or chain 20 serves to prevent spreadingor binding of the standards or stakes, asbefore stated.
